✨ Day 3 of my OOPs in C++ journey Today’s topic: User Defined Data Structures I implemented my own version of a Vector class in C++. 🔹 Key things I practiced: Dynamic array allocation Doubling capacity when the vector is full Adding and removing elements Accessing elements by index with proper validation Printing all elements This helped me understand how STL’s vector might work internally and gave me a deeper appreciation for data structure implementation in C++. Excited to continue building step by step. 🚀 #Cplusplus #OOP #DataStructures #CodingJourney
